Maintaining Your Scale

Cleaning Your Scale

Before you use your scale for the rst time, and if your scale has not been used

for an extended period of time, please check the scale to make sure it is function-

ing correctly. If you nd that your scale is not functioning correctly, please contact

Hopkins Medical Products for assistance. Always examine your scale to make

sure that there are no obvious signs of damage. Always inspect the AC Adapter

to make sure the cord is not cut, abraded, or frayed and the prongs in the plug

and the connector jack are not bent or corroded. Also check the battery compart-

ment to make sure there is no corrosion. If you are not going to use your scale

for an extended period of time, please remove the batteries to prevent corrosion

(battery compartment corrosion is not covered under the limited warranty.)

To perform a calibration, place your scale on a sturdy, level surface and make

sure the batteries are installed, or that the AC Adapter power supply is connected.

To calibrate your Hopkins

Baby Scale you will need two certied weights: one

10kg weight, and one 20kg weight. A certied weight set is available through

Hopkins

Medical Products (Item #685297).

Calibration

Follow these guidelines for proper cleaning of your scale. Improper cleaning

methods may damage your scale and void the warranty.

• Always remove the batteries and disconnect the AC Adapter before cleaning.

• Never immerse your scale in water or any other liquid.

• Never use isopropyl alcohol or any solvent to clean the LCD display.

Always wipe with a clean, soft cloth.

• You may clean the external surfaces of your scale with a mild soap and water

solution and a clean, lightly damp cloth. Always be sure to keep any liquid

from pooling anywhere on the scale. Wipe dry with a clean, soft cloth.

• To sterilize your scale, you may wipe the external surfaces with Sanizide

disinfectant (available as wipes - Item #694826BX, or spray bottle - Item

#694810). Take care to avoid the LCD screen when using disinfectant.

press and hold both the "LB/KG"

button and the "ON/TARE" button

simultaneously until the LCD

screen displays "CAL".

very stable surface. It is important

for the scale to be stable and level

in order to preform an accurate

a series of calibration numbers.

These numbers will begin to

stabilize and will begin to uctuate

by only a few digits. Press

the "ON/TARE" button when

the number is only uctuating

minimally.

4. The LCD screen will briey

ash "C10" and then display "0".

5. Place a 10kg certied weight

on the scale and wait until the

calibration numbers stabilize

again.

6. Press the "ON/TARE" button

again once the numbers have

stabilized as before and are only

uctuating minimally.
